PHP Noob need help.

The following code apparently outputs two arrays, one called $directories and one called $files.

In my template page there is "if (is_Array($directories))" and "foreach ($directories as $v)" and "if (is_Array($files))" and "foreach ($directories as $f)" to be able to display the page differently if the directories or files array is being used and to call variables with $v['FILENAME'].

Everything works great. However, in order to get the "if (is_Array($files))" page looking the way I want I need to call a variable from the $directories array. I need access to the $v['FILENAME']. This variable is already in the $files array as $f['DIR'] but it adds ./ to the front and / to the back of the variable.

How do I add a new variable to the $files array that is equal to $v['FILENAME'] or how do I strip the ./ and / from the $f['DIR'] variable in my templay file?

Any help is greatly appreciated.

The easiest and most readable way to strip those chars is:

$temp = ltrim($f['DIR'], "./");
$temp = rtrim($temp, "/");

Is that what you need?

Good luck,
Ty

 

I think so. Let me test it. Thanks.

 

Works great. Awesome. Thanks.
